Bike Park Wales and a first world problem

So about to take my first trip trip to bike park wales and I have a question for the stw collective. Which bike would be the best option. I have a mini DH bike 180mm travel which I was planning to take but I have heard that the trails are better enjoyed on a long travel trail bike so do I take the 150mm travel. I am hoping to ride as many of the trails as possible inc the easier of the blacks advice would be appreciated. And b4 anybody asked I can't take both!

150mm. One of the blues and one reds are pedally. You will enjoy on whatever you ride tho and a 150mm will easily cope with the black runs.
As above, punctures galore, but that's prob me casing everything

Yep, 6 inch or so is the ideal, unless you're planning on shuttling up the hill all day under your own steam. Even then....

Not sure of the need to change tyres. I ran my usual Rubber Queens with no problem at all. That said, group of four of us, I was the only one not to puncture....Maybe I'm just light on my tyres. (Not on my feet, I hasten to add!)
